| Abstract: | The electromagnetic PT excited ferroresonance in neutral point ungrounded system is studied.Themathematical model of PT is established based on the circuit principles.The equivalent circuit of system is simulatedwith a 10kV net model.The behaviors of each phase with ferroresonance are analyzed.Two factors influencingferroresonance are obtained.Simulation result indicates that the occurrence of ferroresonance and neutral voltageamplitude are influenced by the line length and faulted voltage recovery phase. |
